研究目的
Investigating the enhancement of solar hydrogen generation through the incorporation of plasmonic nickel nanoparticles into LaFeO3 photocathodes.
研究成果
Incorporation of Ni nanoparticles into LaFeO3 photocathodes significantly enhances light absorption and photocurrent density due to SPR, leading to more than double the hydrogen production compared to untreated photocathodes. Optimal Ni nanoparticle size and concentration were identified for maximum efficiency.
研究不足
The study is limited by the potential agglomeration of Ni nanoparticles at higher concentrations, which may reduce SPR performance and electrode/electrolyte interface effectiveness.
